Ferrofluid : Materializing Magnetic Fields

March 29th, 2005 | Filed under: Design, Mapping, Materials, Mathematics | 3 Comments »

Ferrofluid, often used as a mechanical damper by electronically controlling its viscosity, is also a great visualization tool as it responds the surrounding magnetic fields in 3-dimensions. Make some at home, or buy some online and watch it rapidly react to magnetism.

    Now, I knowwww. This is the type of liquid that was used in an art exhibit in Madrid Spain about three years ago. A magnet of variable power created some very interesting shapes…. Yup. A memory.
